The correct answer to this open question is the following.
Had the terms of the Treaty of Versailles actually been enforced, could Hitler's rise to power has been stopped, or was the Treaty flawed from the very beginning?
I consider that the Treaty was flawed from the very beginning because the Allied forces such as France and Great Britain did not really want a good peace treatment. They were hungry for vengeance.
After the war ad the treaty, the German economy was in awful conditions. Germany had to pay costly war reparations and lost land and resources, We could say that Germany was in a state of economic decline​.
In simpler words, Germany was completely devastated. Economically, politically, and morally devastated. The European countries that won the war met at Versailles, France, close to Paris, to hold the peace conference. US President Woodrow Wilson shared his 14 points to establish peace but the issue was that European countries -more than peace- wanted retribution and reparations. That is why they made Germany paid millions in wae reparations for the damage caused.
This represented the beginning of the German hatred that years later allowed the appearance of Adolph Hitler.
